Stringent emissions regulations over the world represent the challenge for the (automotive industry) vehicle manufacturers to make engines which will contribute considerably to environmental protection and the conservation of energy resources, and thus the vehicles are obtain and pleasurable for drive.
Turbochargers come to meet with this challenge and give contribute to the end user.
Compared with a naturally aspirated engine of identical power output, the fuel consumption of a turbo engine is lower, as some of the normally wasted exhaust energy contributes to the engine’s efficiency.
In standard application the power output of a turbocharged engine is doubled which is considerable, and for the result it has faster response in drive. Turbochargers also have influence on the power output loss so that at higher engine speeds, more exhaust gas at lower pressure can be passed through the turbine, which insures advantage to trucks, generators and industrial engines with turbocharged engines.
Turbochargers recycling energy which engines produced, by transformation more of exhaust gas energy in power output with less frictional and thermal losses. Compared with a naturally aspirated engine the fuel consumption of a turbocharged engine is lower. The ratio power-to-weight of the exhaust gas turbine engine is much better than that of the naturally aspirated engine. The turbocharged engine’s installation space requirement is smaller than that of a naturally aspirated engine with the same power output.
Whereas, turbochargers supplied more air mass into engine’s combustion chamber, the combustion is easier, plain, and also emission is lower. Today, the turbocharged diesel engines in comparison with naturally aspirated engines have CO2 and NOx emissions about 50 % lower.
Turbochargers delivered more power output, which transforms in improvement vehicle’s performance on a road, and make driving enjoyable.
The high – altitude performance
The turbine engine performance at high – altitude is significantly better. The lower air pressure at high altitudes can produce the power loss of a naturally aspirated engine. In contrast, the performance of the turbine improves at high altitude as a result of the greater pressure difference between the pressure of the turbine and the ambient pressure at outlet which is lower with the higher altitude. The lower air density at the compressor inlet is largely equalized. Hence, the turbine engine has barely any power loss at higher altitude.
The noise level
Because of reduced overall size, the sound-radiating outer surface of a turbo engine is smaller; it is therefore less noisy than a naturally aspirated engine with identical output. The turbocharger itself acts as an additional silencer.
